Place a Piece of tape over the Hole in the back left corner of the fridge compartment. You may have to poke a small hole or two in the tape to acheive the desired tempurature.
Answer the question is 1/2 or 4/5 colder?
Generally the freezer temp is the REAL temp of the unit. Fans, dampers and manual control levers let some of that cold freezer air into the refer compartment to cool it. Check your owners manual for damper operations if you have one. If you have a refer temp control all that does is control a damper to let the cold freezer air into the compartment. Also make sure you don't block off any of those vents in the refer or freezer compartment or bad air circulation can occur.
Your Hotpoint fridge is designed to operate at a temperature ranging from 0.5 degrees in the coldest part up to 5 degrees inthe warmest part.
